加载并单击隐藏/显示div [英] on load and on click hide/show div

问题描述

我想做的是在加载时隐藏除#p0以外的所有段落. 另外，如果用户单击同级跨度，我想显示一个段落，并隐藏所有其他段落

What I want to do is to have all paragraphs but #p0 hidden on load. Additionally I want to show a paragraph if user clicks on it's sibling span, and hide all other paragraphs

<ul>
   <li>
      <h1>
        <span id="span0">Lorem</span>
        <p id="p0">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span1">Lorem2</span>
        <p id="p1">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span2">Lorem3</span>
        <p id="p2">Lorem ipsum dolor sit amet,</p>
      </h1> 
   </li>
...

推荐答案

$('p:not("#p0")').hide();

$('span').on('click',function() {
    $('p').hide();
    $(this).next('p').show();
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<ul>
   <li>
      <h1>
        <span id="span0">Lorem</span>
        <p id="p0">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span1">Lorem2</span>
        <p id="p1">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span2">Lorem3</span>
        <p id="p2">Lorem ipsum dolor sit amet,</p>
      </h1> 
   </li>
 </ul>

如果您希望将其与页面上其他p/span隔离开来，则可以使用^=) ...

If you wish to isolate this from other p's / span's on the page you could use the 'prefixed-by' attribute selector (^=) ...

$('p[id^="p"]:not("#p0")').hide();

$('span[id^="span"]').on('click',function() {
    $('p[id^="p"]').hide();
    $(this).next('p[id^="p"]').show();
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<ul>
   <li>
      <h1>
        <span id="span0">Lorem</span>
        <p id="p0">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span1">Lorem2</span>
        <p id="p1">Lorem ipsum dolor sit amet,</p>
      </h1>
   </li>
   <li>
      <h1>
        <span id="span2">Lorem3</span>
        <p id="p2">Lorem ipsum dolor sit amet,</p>
      </h1> 
   </li>
 </ul>
